EVs & Geography: Trends in Energy and Emissions Reduction
Can an EV’s Location Determine its Emissions Performance?

How does an electric vehicle’s (EV) location affect its overall environmental performance? More specifically, can the state in which it is registered increase or decrease an EV’s emissions? The answer may surprise you. Our latest Perspectives take a look at this phenomenon to see which states and regions stand to gain the greatest environmental benefit from EV adoption, and which areas are the most logical targets for future growth and infrastructure development.
While the electric vehicle market is growing in the U.S., a key industry question is how EVs’ geographic footprint affects their overall environmental impact. Even though the environmental fit is often given as a reason for EV adoption, recent data suggests that variations across state electricity sources yield widely different outcomes on well-to-wheel emissions. This is an important early trend IAA is tracking, as the states and regions that stand to gain the greatest environmental benefit from EV adoption are logical targets for future growth and infrastructure development.
Any quick search for trends in the electric vehicle space is likely to return a host of articles making the case for this industry’s bright future. A recent CCC Trends report found that U.S. sales of new electric vehicles, hybrids, and plug-in hybrids crossed the 100,000-vehicle mark in Q2 2021 for the first time.1 The numbers are quite staggering year-over-year, as the share of sales for this segment doubled compared to 2020.2 In fact, for the first half of 2021, Experian reported that electric vehicle registrations grew by 117.4% year-over-year, to comprise 2.4% of all new registrations.3 While electric vehicles still only account for 0.43% of vehicles in operation, recent trends are painting an optimistic picture for this industry’s future if they continue.4
One interesting aspect to consider in this growing market segment is geography. For example, there are significant global differences in EV adoption, with Europe far outpacing the rest of the world.5 Pew Research Center compared EV market shares globally in 2020 and found that 10% of new vehicle sales in Europe were EVs, compared to 5.7% in China, and 2% in the U.S.6 Some countries are far ahead of the pack on this metric. Norway boasts a 74.8% EV market share of new vehicle sales.7 An analysis by Experian found significant geographic variation within the U.S. alone. California specifically is a driver for adoption in the U.S., as 36.6% of all new vehicle registrations were for EV vehicles in the first half of 2021. Florida is second with 7.5%, followed by Texas with 5.4%, and New York with 5.1%.8 The market behaviors towards EVs in those states is drastically different from states such as North and South Dakota, Wyoming, and West Virginia, which each had market shares of less than 0.1%.9 For perspective, Figure 1 highlights the state-level EV shares of new vehicle registrations for January to June of 2021.10

While there are many questions worth exploring around EV geographic variation, one interesting aspect is the link between individual state energy sources and the environmental benefits of driving EVs. A key argument for driving EVs is that they reduce tailpipe emissions compared to conventional vehicles, thereby lowering the carbon footprint. However, the true environmental impact can be found by analyzing “well-to-wheel” emissions, which encompasses the entire supply chain impact on emissions from energy sources, vehicle manufacturing, distribution, and ultimately the vehicle emissions themselves.11 State geography becomes an important factor due to the use of different electricity energy sources throughout the U.S. The actual benefit of EVs for reducing emissions is far greater in states that use lower-polluting energy sources for electricity generation, such as hydro, wind and solar, compared to states that are heavily dependent on higher-polluting energy sources, such as coal.12 For perspective, the national average annual emissions per vehicle for an all-electric vehicle is 3,783 pounds of CO2 equivalent.13 However, the range across states is very wide, with emissions on all-electric vehicles in West Virginia averaging 8,967 pounds per CO2 equivalent on the high end, and vehicles in Vermont averaging 0 pounds per CO2 equivalent.14 Figure 2 presents the average state-level emissions per all-electric vehicle by pounds of CO2 equivalent.15

This is an important relationship because consumers often cite the positive environmental impact of driving EVs as a key factor in the decision to switch to an EV. A recent 2021 global survey conducted by Ernst & Young found that 41% of individuals looking to buy a car in the next year plan on buying an EV, and a top reason for buying an EV was the environment.16 Notably, they found that 53% of potential EV buyers believed they had a responsibility to reduce their personal environmental impact. 78% said the pandemic had heightened their awareness and concerns about environmental issues.17
So, if the environmental impact of buying an EV is important to consumers, and that impact is linked to individual state energy sources, this suggests that EV growth and adoption might be stronger in states that will see the greatest emissions reduction from these vehicles. This relationship is seen in Figure 3, which maps the EV share of new vehicles in each state against all-electric vehicle emissions. This figure suggests there is some evidence that states with higher EV market shares tend to have lower all-electric per vehicle emissions. However, given the early stage of EV adoption in the U.S., this is a preliminary trend that is far from statistically sound. Another important component of this conversation is the role of infrastructure. If the push for EV adoption by the government is environmentally focused, states with lower-polluting electricity where the biggest emissions benefits of EVs reside could be a viable factor in industry growth. While all of this is preliminary in nature, this is a trend worth watching and monitoring in the coming years if this industry’s growth continues at its current pace.
